I did a search for Starter Beginner Children Kids and nothing came up. So.... I'd like to get a model train set for my kids ages 6 and 7. I don't want to spend a lot of money (under $400). I do not plan on making this a hobby, we have way too many other things on our plate. I do want something of good quality that will last. We'll probably take it out a couple times a year, around Christmas and maybe other times. Probably set it up on the carpet or hardwood floor. If we REALLY got into later, I think we'd go with a smaller scale anyway and mount the track on a board like my Dad did with me for our HO set. But I don't have time to do that in the foreseeable future. I ran across an article by a model railroad enthusiast. He recommended O Gauge 3-rail starter sets. Specifically he recommended MTH R-T-R Rail King sets over Lionel as having the better set. The only problem is, they'd LOVE having the Polar Express which appears to be Lionel exclusive. Would like some bells and whistles (literally) but don't want to go overboard. Would do the knowledgeable enthusiasts recommend going with? Is there that much of a difference in O-Guage Starter Sets between MTH and Lionel?
